I can't think of a soundtrack as a whole, but there are songs that just make me happy. The theme song to Dandelion 'Yet, I Can't Stay' is awesome, and I think at the end of Idol Days Sim Date SquaDus's cover of 'Rolling Girl' plays. I single those two songs out as I listen to them outside of playing the games. The cover of 'Rolling Girl' is one of my favorite songs in general I think.
